LinkedIn has begun informing Lynda.com users of a data breach, emailing customers to say that "an unauthorized third party breached a database that included some of your Lynda.com learning data, such as contact information and courses viewed."

The company says that there is no evidence to support the thought that passwords were included in this data, and it is simply notifying users out of caution. In fact, the email doesn't even tell the user to change their password. Here's the full text:

We recently became aware that an unauthorized third party breached a database that included some of your Lynda​.com learning data, such as contact information and courses viewed. We are informing you of this issue out of an abundance of caution.

Please know that we have no evidence that this data included your password. And while we have no evidence that your specific account was accessed or that any data has been made publicly available, ​we wanted to notify you as a precautionary measure.

If you have questions, we encourage you to contact us through our Support Center.

Other than the emails that users are receiving, neither LinkedIn nor Microsoft have issued official statements. We've reached out to both companies for comment, as well as clarification on when this happened, how many users were affected, and what type of data was taken. Naturally, we're not expected to hear anything until Monday.

Update: A LinkedIn spokesperson has issued the following statement to Neowin:

We recently became aware that an unauthorized third party ​accessed a database that included Lynda.com ​user data. As a precautionary measure, we reset passwords for the less than 55,000 Lynda.com users affected and are notifying them of the issue. We’re also working to notify approximately 9.5 million Lynda.com users who had learner data, but no password information, in the database. We have no evidence that any of this data has been made publicly available and we have taken additional steps to secure Lynda.com accounts.
